I want to buy this specific gateway computer because it has a decent CPU. For anyone who wants to know it's a gateway DX4870-UR348. I need a minimum of 400W PSU for the graphics card I want to buy, and it only has a 300W PSU. I used a calculator and I'll need at least 324W according to that. I decided I will get the standard 500W PSU, but how will I know if it fits without buying the PC first (I want to buy them all at once so it has free shipping and a coupon)? My friend had a problem where he bought a new one and it didn't fit in a prebuilt computer.

No way to tell until you get it, open it up and measure.
Gateway/Dell/etc are notorious for having non-standard size cases and mounts.

But if you're replacing parts on a brand new machine, why not build from scratch with the actual parts you want?

Just because I need a different power supply? Plus I don't want to buy a motherboard and a OS especially if I can just get them already installed and bios operating normally this way. It's not cost effective and a pain to build my own computer. All I need is a different power supply...

The question is - what other parts are substandard on that Gateway? What motherboard is it? Is the RAM configured correctly (2 x 4GB vs 1 x 8GB)? USB 2 or USB 3?

Building it yourself is NOT a pain, and you can get exactly the parts you want.

It has both USB2 and USB3 and I admit I know absolutely nothing about motherboards: chipset Intel B75, this good or bad?
The only thing I wanted to do with the gateway was replace the power supply and buy a decent graphics card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814202011

It's 359 right now on newegg but it keeps bouncing around from 329-359... It was 329 last week, and then two days ago. Their prices are really crazy and unstable I guess.
329 at it's lowest, 100 for the gpu, and then 40-60 for a 500w power supply, 490 max.
I'm not trying to nitpick with you, but I'm on the "low budget plan" so to speak
